Are we forgetting that many, if not most of the successful and legitimate altcoins were also created by newbie accounts? When Sunny King launched Peercoin, he was just a newbie with 11 posts. Later on he would go on to develop Primecoin. The [ANN] threads for Nxt, Qora, and Auroracoin were all posted under newbie accounts for anonymity reasons. Dogecoin was as well, although the creator of that coin hasn't chosen to remain anonymous.
